I bought 6 for the same breeding question in my 20. I am curious EAT YOUNG vs SLOW GROWING, cuz it's been a few months. I could be even slower because my 20 seems out of snails except the occasional MTS, have a 10 gal growing food lol

Shrimp and snail junkie... What can I say, I like the little things in life.

They are very slow to grow and burrow right after hatching until they gain some size. Cannibalization is rare if they have sufficient other foods present. It a bit hotly debated as to if they do or do not... they definitely will eat a dead animal (fish or snails) and they will definitely prefer other snail types to their own type.

I've never seen active cannibalism in assassins, I've seen young and adults feeding on scraps together. Doesn't mean it wouldn't happen though, as with any other species I'm sure they'd snack on dead ones.

They are a type of Whelk not a snail so maybe they don't like the taste of themselves . They will breed if conditions are good 23+ temp and plenty of food, as the food runs down the breeding slows. I started with 5 and now I have hundreds. I feed them on rolled up frozen brine shrimp placed under a small glass as its fun watching them burrow their way in
